shell coal gasification process - an overview

shell coal gasification process - an overview

The Shell coal gasification process (SCGP) can operate on a wide variety of feedstocks. It consists of three principal stages: 1. Gasification (partial oxidation), in which the feedstock is converted to syngas in the presence of oxygen and a moderating agent (steam) in a refractory-lined gasification reactor. 2

The figure of gasification reactions and transformations illustrated the concept of coal gasification, and noted resulting composition of syngas. This can vary significantly depending on the feedstock and the gasification process involved; however typically syngas is 30 to 60% carbon monoxide (CO), 25 to 30% hydrogen (H 2), 0 to 5% methane (CH 4), 5 to 15% carbon dioxide (CO 2), plus a lesser
